Abstract

Аim. To analyze the significance of estrus synchronization as a biotechnological approach to managing the reproduction of breeding stock and to determine its impact on conception rates, the regularity of the reproductive cycle, and the efficiency of utilizing animals’ genetic potential. Methods. The study was based on theoretical analysis, systematization, and generalization of domestic and international scientific sources on reproductive physiology, neuroendocrine regulation of the female estrous cycle, and modern methods of reproductive management. Results. The physiological foundations of the female estrous cycle and the role of the coordinated interaction of the hypothalamus, pituitary gland, and ovaries in ensuring timely estrus and ovulation were summarized. The mechanisms of action of hormonal preparations and the effectiveness of synchronization protocols were analyzed. It was established that their application contributes to shortening the service period, increasing conception rates after the first insemination, optimizing the organization of artificial insemination, and ensuring uniform offspring production. Conclusions. Estrus synchronization is an effective tool for intensifying the reproduction of breeding stock which, when used rationally, ensures improved reproductive performance and the economic efficiency of farms.
